Question

Q5.Evaluate the following divisions:
(a) (3b – 6a) ÷ (30a – 15b)
(b) (4x2 – 100) ÷ 6(x + 5)

Answer 1

Step-by-step explanation:

a. 3b-6a/30a-15b

15/3b-30/6a

5b-5a

= 5a-5b

(b) (4x2 – 100) ÷ 6(x + 5)

8-100/6x+30

6x=8-100/30

6x=8-10/3

6x=-2/3

x=6*2/3

x=2*2

x=4

Answer 2

Step-by-step explanation:

a)3b-6a/30a-15b

15/3b-30/6a

5b-5a

5a-5b

b)(4x2-100)÷6(x+5)

8-100/6x+30

6x=8-100/30

6x=8-10/3

6x=-2/3

x=6*2/3

x=2*2

x=4
